CHAPTER 35 PLANT STRUCTURE, GROWTH, AND DEVELOPMENT Learning objectives The Plant Body 1. Describe and compare the three basic organs of vascular plants. Explain how these basic organs are interdependent. 2. List the basic functions of roots. Describe and compare the structures and functions of fibrous roots, taproots, root hairs, and adventitious roots. 3. Describe the basic structure of plant stems. 4. Explain the phenomenon of apical dominance. 5. Describe and distinguish between the leaves of monocots and eudicots. 6. Describe the three tissue systems that make up plant organs. 7. Describe and distinguish between the three basic cell types of plant tissues. 8. Explain the functional relationship between a sieve-tube member and its companion cell. The Process of Plant Growth and Development 9. Distinguish between determinate and indeterminate growth. Give an example of each type of growth. 10. Distinguish between annual, biennial, and perennial plants. 11. Explain this statement: “In contrast to most animals, which have a stage of embryonic growth, plants have regions of embryonic growth.” 12. Distinguish between the primary and secondary plant body. 13. Describe in detail the primary growth of the tissues of roots and shoots. 14. Describe in detail the secondary growth of the tissues of roots and shoots. 15. Name the cells that make up the tissue known as wood. Name the tissues that comprise the bark. Mechanisms of Plant Growth and Development 16. Explain why Arabidopsis is an excellent model for the study of plant development. 17. Define and distinguish between morphogenesis, differentiation, and growth. 18. Explain why (a) the plane and symmetry of cell division, (b) the orientation of cell expansion, and (c) cytoplasmic microtubules are important determinants of plant growth and development. 19. Describe how three classes of organ identity genes interact to produce the spatial pattern of floral organs in Arabidopsis.
